Avid Mbox flashing leds

[ym2149]

This weekend was spent making music in a cottage in the swedish countryside, but that was nearly ruined by my Mbox (3:rd gen) suddenly going american christmas on us when I switched mics from one condenser to another. All the leds were flashing like it does when first starting up, but it didn't stop flashing.

We eventually tried connecting it to an old PC just to see what happened, and the flashing stopped! Reconnected to my mac, and it worked again! This happened once more during the eveneng and I could only "reset" it by connecting it to the other PC. Nothing else worked; leaving the mbox disconnected for a while, rebooting, booting the mac into Windows...

Is there another way to reset the Mbox in case there is no other computer around? I should probably not switch mices like that with phantom power on, right, but if I do, is there a way?

Thanks!
